Can I do a 13 hour fast to lose weight ?

I’m trying to get back into the habit of doing IF but since I started a new job I can only get to 13 before I break my fast with coffee. I typically go 18-20 hours during the weekend but during the week it’s tough to past 13 hours. Any advice would be appreciated. via /r/intermittentfasting https://ift.tt/DJUcxkg https://ift.tt/wLsbQIq
